Mesoporous silica SBA-15 materials of high specific surface area (similar to 700 m(2) g(-1)) were synthesized by using block copolymer Pluronic P123 as template and tetraethoxysilane as silica source. The obtained materials were characterized by XRD, nitrogen adsorption desorption measurements, SEM, EDS and AFM analysis. It was found that small modifications of synthesis conditions influenced the morphological features of the synthesized SBA-15 samples. The SEM analysis had shown that the SBA-15 synthesized at lower temperature and longer time of reaction (80 degrees C, 48 h) provided elongated rod-shaped grains about 1 mu m long. The other sample synthesized at higher temperature and shorter time of reaction (100 degrees C, 24 h) had rounded grains and grains of regular spherical shape with diameters ranging from 0.5 to 2 mu m. The EDS analysis confirmed that the particles of both synthesized samples were of the SiO2 content. In addition, the AFM analysis had shown different surface m...orphologies of the materials synthesized under various conditions.
